Key Calculus Terms and definitions covered in this textbook

P(A or B) = P(A) + P(B) - P(A and B). If A and B are mutually exclusive events, then P(A or B) = P(A) + P(B)

• Composition of functions

(f ? g) (x) = f (g(x))

• Cosine

The function y = cos x

• Dependent event

An event whose probability depends on another event already occurring

• equation of a quadratic function

ƒ(x) = ax 2 + bx + c(a ? 0)

• Expanded form of a series

A series written explicitly as a sum of terms (not in summation notation).

• Focal width of a parabola

The length of the chord through the focus and perpendicular to the axis.

• Integrable over [a, b] Lba

ƒ1x2 dx exists.

• nth root of unity

A complex number v such that vn = 1

• Partial fraction decomposition

See Partial fractions.

• Permutation

An arrangement of elements of a set, in which order is important.

• Point-slope form (of a line)

y - y1 = m1x - x 12.

• Projectile motion

The movement of an object that is subject only to the force of gravity

Any one of the four parts into which a plane is divided by the perpendicular coordinate axes.

A function that can be written in the form ƒ(x) = ax 2 + bx + c, where a, b, and c are real numbers, and a ? 0.

• Quartile

The first quartile is the median of the lower half of a set of data, the second quartile is the median, and the third quartile is the median of the upper half of the data.

• Repeated zeros

Zeros of multiplicity ? 2 (see Multiplicity).

• Second quartile

See Quartile.

• Terminal point

See Arrow.

• Unit vector

Vector of length 1.
